Bladder polyp

Bladder polyps are abnormal, protruding tissue growths that can occur in the lining(mucous membrane) of the bladder wall.

Polyps can be both benign (non-cancerous) and malignant (cancerous).

Imaging cannot determine if a polyp is benign or malignant, and thus direct visualization (cystoscopy) of the polyp is needed for further characterization.
